在宣布計劃擴(kuò)大TD-LTE試驗網(wǎng)絡(luò)兩個月之后，中國移動本周表示，將有7家供應(yīng)商為這種先進(jìn)網(wǎng)絡(luò)提供設(shè)備，但中國移動未披露將如何分工。 中興通訊和阿爾卡特-朗訊在一天后急忙宣布，都從中國移動贏得了一項TD-LTE合同。中國移動是全球第二大無線網(wǎng)絡(luò)運營商。 其它為TD-LTE網(wǎng)絡(luò)提供設(shè)備的中標(biāo)企業(yè)包括：華為，愛立信，諾基亞西門子通信(MSN)，New Postcom Equipment Co.和大唐移動。 據(jù)報道，中國移動的這次招標(biāo)內(nèi)容包括大約2萬個基站和5.2萬個載頻。中國移動這次采購的TD-LTE設(shè)備將用于在13個中國城市擴(kuò)大TD-LTE試驗網(wǎng)絡(luò)。 中興透露其將在五個中國城市建設(shè)中國移動的TD-LTE網(wǎng)絡(luò)：北京，天津，廣州和沈陽。其中將包括1.3萬個以上的載頻。 阿爾卡特-朗訊表示贏得一項合同，占TD-LTE試驗網(wǎng)絡(luò)基站的最大份額。根據(jù)這項合同，阿爾卡特-朗訊的中國子公司上海貝爾將在2013年初在上海、南京和青島提供大約3千個基站。 中國移動擁有7億多個用戶，一直在積極擴(kuò)大TD-LTE試驗網(wǎng)絡(luò)。到2012年底，試驗網(wǎng)絡(luò)將布署2萬個基站，覆蓋總計人口達(dá)1.5億人的13個城市。 隨著智能手機(jī)需求激增，中國移動急于推出TD-LTE網(wǎng)絡(luò)。據(jù)市場調(diào)研公司Gartner，中國是全球最大的智能手機(jī)市場，占全球智能手機(jī)出貨量的四分之一。 中國在移動數(shù)據(jù)服務(wù)方面也領(lǐng)先于全球市場。阿爾卡特-朗訊表示：“阿爾卡特-朗訊布署的新的TD-LTE網(wǎng)絡(luò)，將提高中國移動的網(wǎng)絡(luò)速度、容量和質(zhì)量?！痹摴?yīng)商亦表示，它也將讓中國移動能夠縮小設(shè)備尺寸和降低功耗。 與中國的TD-SCDMA標(biāo)準(zhǔn)相比，推出TD-LTE是為了提供全I(xiàn)P能力、更快的響應(yīng)時間和更低的延時，最大數(shù)據(jù)下載速度高達(dá)100 Mbit/s。 中國移動與日本軟銀都在興建TD-LTE網(wǎng)絡(luò)。軟銀本周以201億美元收購美國移動運營商Sprint Nextel 70%股份，這是迄今日本企業(yè)收購?fù)鈬窘灰椎淖畲笠?guī)模。 本文授權(quán)編譯自EE Times，版權(quán)所有，謝絕轉(zhuǎn)載 編譯：Luffy Liu 參考英文原文：China Mobile selects 7 suppliers for TD-LTE trial, by Junko Yoshida

{pagination} China Mobile selects 7 suppliers for TD-LTE trial Junko Yoshida Two months after announcing plans for an expanded TD-LTE trial network, China Mobile said this week that seven manufacturers will supply gear for the advanced network, but stopped short of disclosing how the work will be divided. A day later, ZTE and Alcatel-Lucent raced to announce that each had won a TD-LTE contract from the world???s largest cellular network operator. Other winning bidders to help build the TD-LTE network include: Huawei Technologies, Ericsson, Nokia Siemens Networks (NSN), New Postcom Equipment Co. and Datang Mobile Communications Equipment Co. (Datang Mobile). China Mobile???s tender reportedly included contracts for some 20,000 base stations and 52,000 carrier sectors. The TD-LTE devices purchased by China Mobile will be deployed in an expanded TD-LTE trial network in 13 Chinese cities. ZTE revealed that it will construct China Mobile???s TD-LTE networks in five Chinese cities: Beijing, Tianjin, Guangzhou, Shenzhen and Shenyang. They will include more than 13,000 carrier frequencies. Alcatel-Lucent said it won a contract to deliver ??úthe largest share of basestations??ù for TD-LTE trial network. Under the contract, Alcatel-Lucent Shanghai Bell, Alcatel-Lucent???s China subsidiary, will supply about 3,000 basestations in Shanghai, Nanjing and Qingdao in early 2013. With more than 700 million subscribers, China Mobile has been aggressively pursuing an expanded TD-LTE trial network. By the end of 2012, the trial network will deploy 20,000 basestations covering 13 cities with a combined population of 150 million people. China Mobile is in a hurry to roll out TD-LTE networks as smartphone demand soars. China is the world???s largest smartphone market, accounting for one-quarter of global smartphone shipments, according to market researcher Gartner. China also leads the global market for mobile data services. "The new TD-LTE network deployed by Alcatel-Lucent will increase the speeds, capacity and quality of China Mobile's network,??ù Alcatel-Lucent claimed. It will also give China Mobile the ability to operate with a smaller footprint and lower power consumption, the supplier added. Compared to China's TD-SCDMA spec, TD-LTE is designed to offer full IP capability; faster response time and lower latency, with peak downlink data rates of 100 Mbit/s. TD-LTE networks are being built by both China Mobile and Japan's Softbank. Softbank this week reached a deal to buy 70 percent of U.S. mobile carrier Sprint Nextel Corp. for $20.1 billion in the largest ever foreign acquisition by a Japanese company.
